When applied within a low-strength electric field (±12 V/cm) with a low current density (±2.1 mA/cm2),
several industrial biocides exhibited enhanced killing action against Pseudomonas aeruginosa biofilms grown on
stainless steel studs. Biocide concentrations lower than those necessary to kill planktonic cells of P. aeruginosa
(1, 5, and 10 ppm of the active ingredients of kathon, glutaraldehyde, and quaternary ammonium compound,
respectively) were bactericidal within 24 h when applied within our electrified device.
